🧭 BGP Management

Policy-Driven Routing, Anycast & Resilient Interconnect

Border Gateway Protocol (BGP) is the policy brain of your network. SolveForce designs, deploys, and operates BGP so your traffic takes the best path—not just the shortest hop—with security, stability, and observability built in.

Where this fits in the SolveForce model:
🌐 Connectivity (Grammar) → Connectivity • 🖧 Networks & DCs → Networks & Data Centers
☁️ Cloud (Syntax) → Cloud • 🔒 Security (Semantics) → Cybersecurity
🔗 On-ramps → Direct Connect • 🏢 Interconnect → Colocation

🎯 Outcomes (What BGP Management Delivers)

  • Deterministic traffic engineering (TE)control inbound and outbound flows across carriers, regions, and clouds.
  • High availability & fast convergencemultipath/ECMP, BFD, graceful restart, PIC-like patterns.
  • Security by designRPKI/ROA validation, IRR-based filters, max-prefix, TTL security, MD5.
  • Anycast & global load routingresilient user entry points for DNS, web, APIs.
  • Observability & evidenceroute analytics, BMP feeds, SLO dashboards, SLA audits.

🧩 BGP Building Blocks (Spelled Out)

  • eBGP / iBGP— External / Internal BGP; eBGP to carriers and clouds, iBGP across your AS.
  • AFI/SAFI— Address Families: IPv4/IPv6 unicast, VPNv4/VPNv6 (MPLS Layer-3 VPN), EVPN (Ethernet VPN), BGP-LU (Label Unicast).
  • ASNs— 2-byte/4-byte Autonomous System Numbers; public or private ranges.
  • Route Reflectors (RR) / Confederations— scale iBGP without full mesh.
  • Next-hop-self, MED, Local-Pref— ensure correct next hop; signal preferred exits; set intra-AS preference.
  • Communities— standard/extended/well-known (e.g., no-export, no-advertise); provider-specific action tags.
  • Graceful Restart / NSF— preserve forwarding while control plane restarts.
  • BFD— Bidirectional Forwarding Detection for sub-second failure detection.
  • Add-Path / Multipath— advertise/select multiple best paths for ECMP/load sharing.
  • Max-Prefix— protect sessions from accidental route floods.

🚦 Policy Toolkit (Traffic Engineering You Can Prove)

Outbound control (your AS → the world)

  • Local Preference (LOCAL_PREF)primary knob inside your AS; higher wins.
  • MED (Multi-Exit Discriminator)hint to neighbors which link to prefer.
  • Per-prefix communitiessend provider actions like “prefer/backup,” “prepend n times,” “blackhole this /32”.

Inbound control (the world → your AS)

  • AS-PATH prependingmake a path look longer to de-prefer it.
  • Selective advertisementannounce specific prefixes to specific upstreams.
  • Provider communitiesleverage carrier docs to influence their path selection.
  • Hot-potato vs. Cold-potatoegress quickly to nearest exit vs. carry traffic further for performance—choose per app.

We document policy as code + diagrams, so intent, attributes, and communities are unambiguous.

🌍 Anycast & Global Load Routing

Publish the same IP prefix from multiple sites/regions so users hit the closest healthy entry point.

  • Use casespublic DNS, CDN/web edges, API front doors, auth services.
  • Health-based withdrawintegrate monitoring → withdraw BGP at sick sites.
  • Consistencysame origin, security policy, and route attributes at every pop.
  • PairingsAnycast + CDN for content; Anycast + WAF/DDoS for protection.
    → CDN • DDoS Protection

☁️ Cloud On-Ramps & Hybrid (BGP in the Colo)

Tie AWS Direct Connect, Azure ExpressRoute, Google Interconnect into your AS:

  • BGP peeringwith cloud routers (ASNs); use VRFs to separate private/public flows.
  • Transit hubsAWS Transit Gateway, Azure ExpressRoute Gateway, Google Cloud Router.
  • Redundancydual cross-connects, dual ports (LAG where supported), dual sites/metros.
  • Policytag “golden” prefixes, pin critical routes to the nearest on-ramp POP.

🧠 MPLS / EVPN / SD-WAN Interop

  • MPLS L3VPN (VPNv4/VPNv6)carrier or DIY core; leak routes between VRFs where needed. → MPLS
  • EVPNmodern L2/L3 service; scalable multi-site VXLAN fabrics and inter-DC mobility.
  • SD-WANoverlay steering by loss/latency/jitter; BGP advertises underlay/overlays and default-originate where appropriate. → SD-WAN

🛡️ BGP Security Hardening (No Compromises)

  • RPKI / ROA validationdrop invalids; prefer valids.
  • IRR-based prefix filtersbuild allowlists from route registries.
  • Bogon filtersblock unallocated/reserved space; reject private ASNs on eBGP ingress.
  • TTL Security (GTSM) & MD5 authmitigate spoofing/session hijack.
  • Max-prefix & dampeningcontain leaks and flap storms.
  • uRPF at edgesUnicast Reverse Path Forwarding complements BGP filters.
  • RTBH / FlowspecRemote-Triggered Black Hole and BGP Flowspec to signal scrubbing or drop attacks at scale. → DDoS Protection

Security evidence (RPKI state, filter hits, max-prefix events) is shipped to SIEM/SOAR. → SIEM / SOAR

🔎 Observability & Evidence

  • Graceful Shutdown / GRdrain traffic before session resets.
  • Add-Path/multipathreduce path churn impact; keep ECMP stable.
  • Backout planssnapshot configs, version control, and automatic rollback on error.
  • Blackhole drillsRTBH/Flowspec exercises with your scrubbing partner.
  • Convergence< 3–5 s for edge failures (with BFD); < 30 s core policy changes.
  • Session healthflap rate < 2/hour per peer; max-prefix never hit in steady state.
  • Anycast reachabilityhealth-based withdraw < 60 s end-to-end.
  • Security posture100% RPKI validation enabled on Internet-facing peers; 0 invalids accepted.

Key terms in plain language

Open a term for a concise explanation of language used on this page.

Latency

The time it takes data to travel between two points. Lower latency improves voice, video meetings, cloud applications, gaming, and other real-time services.

Service-Level Agreement (SLA)

A provider’s written commitment covering service targets such as availability, response time, repair time, and sometimes financial credits when commitments are missed.

SD-WAN

Software-defined wide area networking. It manages multiple connections and chooses paths based on application needs, performance, and policy to improve resilience and control.

MPLS

Multiprotocol Label Switching, a private-network technology that directs traffic along managed paths. Organizations use it for predictable connectivity between locations.

VPN

A virtual private network creates an encrypted connection across another network, commonly allowing remote users or offices to access private resources securely.

Cybersecurity

The practices and controls used to protect identities, devices, networks, applications, and data from unauthorized access, disruption, or manipulation.

Colocation

Placing customer-owned servers and network equipment in a professionally operated data center that provides power, cooling, physical security, and connectivity.

Content Delivery Network (CDN)

A distributed system that serves website or application content from locations closer to users, improving speed, resilience, and capacity.
